name: Apple release (macOS DMG)

# Builds, signs, notarizes, and uploads the direct-download macOS build:
#   - a Developer ID–signed, notarized VniDrop-<version>.dmg,
#   - a Sparkle appcast.xml.
#
# The central release workflow publishes these artifacts and updates Homebrew.
#
# The App Store / TestFlight build is NOT produced here — that goes through Xcode
# Organizer / App Store Connect. This workflow only covers direct distribution.
#
# Called by the central tag-release workflow, or run manually to validate the
# signed/notarized direct-download artifact.
